What is SDRAM? SDRAM is an acronym for Synchronous Dynamic Random Access Memory. The term "Synchronous" means that the clock cycle of the memory is exactly synchronized with the clock cycle of the bus. Every calculation and operation a PC performs is timed according to a clock ticking millions of times each second, its clock cycle or megahertz rating. If the memory clock cycle is not in sync with the bus clock cycle, system problems will occur. What is Cache Memory? Cache, pronounced "cash", is a high-speed memory designed to supply the processor with the most frequently requested data and instructions. The information located in the cache memory can be accessed many times faster than information in the system''s main memory. The more information your system can retrieve from the cache memory, the more efficient the system will run. Level 1 (L1) cache, also referred to as Primary Cache, is normally located inside the CPU chip. Level 2 (L2) cache, also referred to as Secondary Cache, was normally located on the system board near the CPU in the past. In today''s systems, both are physically located within the CPU and as a result are not upgradable.

By upgrading your system''s video memory, the resolution on the computer''s monitor can be increased depending upon the limits of the monitor itself. Programs that are graphics intensive will also run faster and have a smoother appearance.
